Harlequins Women ran in 13 tries as they maintained their lead in the Premier 15s table with an emphatic 81-0 win over Firwood Waterloo.
Davinia Catlin (3), Giada Franco, Heather Cowell (2), Tove Viksten (2), Emily Scott, Jess Breach (2), Emily Robinson and Fiona Fletcher all scored.
Their seventh successive bonus-point victory puts them one point clear of Saracens, who won 32-21 at Wasps.
Gloucester are third after a 60-12 win over Darlington Mowden Park Sharks.
In the first league fixtures for a month following the international break, Quins went ahead on a cold, misty morning at Surrey Sports Park after only three minutes through Catlin, with Franco finishing a fine flowing move with 12 minutes gone.
Catlin completed her hat-trick in the second half, while stylish footwork from Scott saw the England international notch a fine individual try.
Sarries also have a 100% record and Canadian Mackenzie Carson powered through under the posts to give them a 10-point lead after eight minutes in the afternoon sunshine at Twyford Avenue.
Hannah Botterman also crashed over to put the visitors 17-6 ahead at the break and further scores from Rocky Clark – against her former club – another for Botterman, and Poppy Cleall in the corner ensured the bonus-point win.
The first meeting of the season between the top two teams takes place at Twickenham Stoop on 14 December.
Gloucester recorded 10 tries in their win, Rachel Lund, Kelly Smith (2), Mia Venner, Ellena Perry, Ellie Underwood (2), Ceri Large, Mo Hunt and Charlie Mae Manns all going over.
In the late kick-off, Loughborough Lightning’s Rachael Woosey ran in a hat-trick of tries in a 34-0 away win at Richmond Women.
Loughborough’s win leaves them sitting fourth in the Premier 15s table.
Women’s rugby analysis from Adam Zoltie at Richmond Athletic Ground
With both teams experiencing an inconsistent start to the season, it was imperative that Richmond and their opponents, Loughborough, returned to league action with vigour after the international break.
Lightning’s scrum half, Jenny Maxwell, epitomised this as she sliced open the home team’s defence within the first eight minutes, following a pick-and-go by Sarah Hunter off the back of a scrum.
Hunter herself embodied her pack’s power and dynamism by jotting down soon after. Her performance, alongside that of the returning Sarah Bonar, allowed Rhys Edwards’ team to dominate up front.
This told more in the scrum, however, as Richmond frustrated them in the line-out, with the returning Fiona McIntosh and skipper Rowena Burnfield impressing.
The day, however, belonged to Loughborough winger Rachael Woosey. The new signing finished off two flowing team moves in each half, which were sandwiched in between a stunning solo effort, to contribute to her hat-trick.
Not to be outdone, fellow wing Rhona Lloyd’s try was also a spectacular score to ensure her side left London with their fourth win of the campaign.
